PHP中POST请求后如何获取HTTP响应头？

我想知道在 PHP 中发出 POST 请求后是否可以在不使用 cURL 的情况下读取/解析 HTTP 响应标头。

我在 IIS7 下有 PHP 5 我用于 POST 的代码是：-

$url="http://www.google.com/accounts/ClientLogin";
$postdata = http_build_query(
    array(
        'accountType' => 'GOOGLE',
        'Email' => '[email protected]',
        'Passwd' => 'xxxxxx',
        'service' => 'fusiontables',
        'source' => 'fusiontables query'
    )
);
$opts = array('http' =>
    array(
        'header'  => 'Content-type: application/x-www-form-urlencoded',
        'method'  => 'POST',
        'content' => $postdata
    )
);
$context  = stream_context_create($opts);
$result = file_get_contents($url, false, $context);

上面，我对 google 进行了简单的 ClientLogin 身份验证，我想获取在标头中返回的身份验证令牌。回显 $result 仅给出正文内容，而不给出包含身份验证令牌数据的标头。

I want to know if it's possible to read/parse the HTTP response header after a POST request in PHP without the use of cURL..

I have PHP 5 under IIS7
The code I use to POST is :-

$url="http://www.google.com/accounts/ClientLogin";
$postdata = http_build_query(
    array(
        'accountType' => 'GOOGLE',
        'Email' => '[email protected]',
        'Passwd' => 'xxxxxx',
        'service' => 'fusiontables',
        'source' => 'fusiontables query'
    )
);
$opts = array('http' =>
    array(
        'header'  => 'Content-type: application/x-www-form-urlencoded',
        'method'  => 'POST',
        'content' => $postdata
    )
);
$context  = stream_context_create($opts);
$result = file_get_contents($url, false, $context);

Above, im doing a simple ClientLogin Authentication to google and I want to get the Auth token which returns in the header. Echo-ing $result only gives the body content and not headers which contains the auth token data.

使用 ignore_errors 上下文选项（文档）：

$opts = array('http' =>
    array(
        'header'  => 'Content-type: application/x-www-form-urlencoded',
        'method'  => 'POST',
        'content' => $postdata,
        'ignore_errors' => true,
    )
);

另外，也许使用 fopen 而不是 file_get_contents。然后，您可以调用 stream_get_meta_data($fp) 来获取标头，请参阅上述链接上的示例#2。

Use the ignore_errors context option (documentation):

$opts = array('http' =>
    array(
        'header'  => 'Content-type: application/x-www-form-urlencoded',
        'method'  => 'POST',
        'content' => $postdata,
        'ignore_errors' => true,
    )
);

Also, maybe use fopen rather than file_get_contents. You can then call stream_get_meta_data($fp) to get the headers, see Example #2 on the above link.

get_headers() 函数可能就是您正在寻找的函数。

您仍然可以使用方便的 file_get_contents 并通过 $http_response_header。

不需要 fopen 和 stream_get_meta_data。

$http_response_header 将在调用 file_get_contents 的范围内填充响应标头。

甚至不需要设置 ignore_errors，因为只有 file_get_contents 的返回值会受到失败请求的影响，$http_response_header 仍然会保留您的 HTTP 401 和 500。

问题中的代码如下所示：

$url = "http://www.google.com/accounts/ClientLogin";
$postdata = http_build_query(
    array(
        'accountType' => 'GOOGLE',
        'Email' => '[email protected]',
        'Passwd' => 'xxxxxx',
        'service' => 'fusiontables',
        'source' => 'fusiontables query'
    )
);
$opts = array('http' =>
    array(
        'header'  => 'Content-type: application/x-www-form-urlencoded',
        'method'  => 'POST',
        'content' => $postdata
    )
);
$context  = stream_context_create($opts);
$result = file_get_contents($url, false, $context);
$headers = $http_response_header; // this is all you have to do!

You can still use the handy file_get_contents and have your headers via $http_response_header.

No need for fopen and stream_get_meta_data.

$http_response_header will be populated with response headers right in the scope where file_get_contents was called.

No need even to set ignore_errors as only the return value of file_get_contents is affected by failed request, $http_response_header will still have your HTTP 401s and 500s.

The code from the question would look like this:

$url = "http://www.google.com/accounts/ClientLogin";
$postdata = http_build_query(
    array(
        'accountType' => 'GOOGLE',
        'Email' => '[email protected]',
        'Passwd' => 'xxxxxx',
        'service' => 'fusiontables',
        'source' => 'fusiontables query'
    )
);
$opts = array('http' =>
    array(
        'header'  => 'Content-type: application/x-www-form-urlencoded',
        'method'  => 'POST',
        'content' => $postdata
    )
);
$context  = stream_context_create($opts);
$result = file_get_contents($url, false, $context);
$headers = $http_response_header; // this is all you have to do!
